Description

A device and method for monitoring the correctness and compliance rate of ankle pump exercise and straight leg raising exercise in patients

technical field

The invention belongs to the technical field of medical aids, and in particular relates to a device and method for monitoring the correctness and compliance rate of patients' ankle pump movement and straight leg raising exercise.

Background technique

Patients after orthopaedic surgery are affected by factors such as anesthesia method, operation time, tourniquet application, and prone position during operation, which can lead to slow venous blood return; stress reaction, surgical trauma, etc. cause vascular intima damage, leading to blood hypercoagulability. It increases the risk of deep vein thrombosis (Deep Vein Thrombosis, DVT), and most patients need to stay in bed for a long time after surgery, resulting in poor blood flow, which further increases the risk of DVT to some extent. Immediately after the operation, the ankle pump exercise and straight leg raising exercise of the lower limbs can be performed, which not only help to exercise the muscle strength of the lower limbs, especially the quadriceps femoris, maintain the stability of the knee joint, and prevent muscle atrophy, swelling of the lower limbs and thrombosis.

Ankle pump exercise specifically acts like a pump through the movement of the ankle joint to enhance the blood circulation of the lower limbs and prevent thrombosis. When doing this action, stretch your knees naturally, try your best to hook and stretch your feet, and repeat; stretch your feet naturally, and forcefully hook your feet for 10 seconds, then stretch your feet with all your strength, and repeat until the pain is not caused. Under the premise of unlimited number of exercises; hook and stretch feet should try to achieve the maximum amplitude, the movements should be as soft and slow as possible, and do both feet at the same time, the effect is better.

Straight leg raising exercise can help exercise the lower limbs, prevent muscle atrophy, lower limb swelling and thrombosis, and help patients get off the ground at an early stage. Joints, the lower limbs on the affected side are as straight as possible, placed on the bed, the toes point to the tip of the nose, the quadriceps muscles are contracted, and the entire lower limbs are tensed. Lift the straight leg and lift it 15 degrees away from the bed surface (the lift is greater than 30 degrees for patients after lumbar spine surgery) for 10 seconds. If it cannot be maintained, continue to raise appropriately, but try not to exceed the contralateral knee joint, slowly lower the lower limbs on the bed, and do not fall off.

However, in current clinical practice, it is found that nurses only instruct patients on the methods and frequencies of ankle pump exercise and straight leg raising exercise through oral or video, but cannot effectively monitor the correct rate and quantity compliance rate of patients' exercise methods. Therefore, it is urgent to design A device and method for monitoring the correctness and compliance rate of patients' ankle pump exercise and straight leg raising exercise.
